each side of said actuating members, a representing the middle arm and aa the outside arms. The several switch-arms are supported by meanswhereby they are insulate from each other and are attached to an ear ofon a supporting-plate a. The actuating members a a each bear contacts ator near their upper ends which are adapted to engage contacts on theoutside arms, and the middle arm bears a contact which is adapted to beengaged by a contact on one of the actuating members. This group ofspring-acting arms, however, operate the local circuits, so that adetail description of the circuits is not necessary, and said group ofswitches is herein referred to as the telephone-switch.

Be it known that I, FRANK M. POTTER, J r., of Rome, county of Oneida,State of New York, have invented an Improvement inTelephone-Switch-Operating Mechanism, of which the followingdescription, in connectionwith the accompanying drawings, is aspecification, like characters on the drawings representing like parts.

I This invention relates to telephone-switchoperating mechanism, and hasfor its object to provide improved means for operating the switchautomatically when the telephone-receiver, or it may be a combinedreceiver and transmitter, is removed from or replaced upon the pivotedhook, which is adapted to receive and support it.

One of the essential objects of my invention is to provide means forsupporting the telephone-hook at either side of the switch-box, and tothis end means are provided for supporting said hook at both sides ofthe box, to either one of which supports said hook may be connected.

Another object of my invention is to improve the construction of theswitch-actuating mechanism.

Figure -1 shows in front elevation the operating mechanism of a group oftelephoneswitches embodying this invention, the pivoted hook beingdepressed. Fig. 2 is a similar view showing the pivoted hook in itselevated position. Fig. 3 is a plan view of the parts shown in Fig. 1.Fig. 4 is a detail of the support for the telephone-switches and guidefor the switch-operating arm. ig. 5 is a detail showing a modificationof the angularly-formed end on the cross-bar. Fig. 6 shows a modifiedform of switch-actuating mechanism. Fig. 7 is a vertical section ofdiverging ends of the springacting arms and thereby operate theswitches. The switch-operating arm b works in a slot a formed in an eara on the supportingplate, and is guided by said slotted ear.

pin b extends radially from the rock-shaft 1), near one or both endsthereof, adapted to be engaged by an extension 0 on the pivoted hook c,which receives upon it the receiver, or combined receiver andtransmitter, which elementis hereinafter referred to as the telephone,or in lieu of said pin the ends of the bar are bent at right angles, asshown in Fig. 5, in both instances, however, angularly formed ends beingproduced. The weight of the telephone depresses the pivoted hook and theextension 0 thereon en ages and lifts the end of the rock-shaft and tereby turns said shaft on its axis in one directhe switch-actuatingmechanism, taken on tion, and also lifts the radially-extended arm thedotted line 7 7, Fig. 6 Fig. 8 is a detail 1) free from the actuatingmembers a aof the switches a. A sprmg d is connected with the rock-shaftfor the purpose of turning it in the opposite direction, and said springis made to encircle the shaft and is permitted to act when the telephoneis removed from the book. At each side of the switch-box a support 6 isprovided for the telephone-supporting hook, which, as shown in Fig. 1,consists of a pair of ears projecting from a base plate to which saidhook is pivoted, and it will be understood that said hook is detachablyconnected to either one of said supports.

Referring to Figs. 1 to 4, a represents the group of switches,comprising a plurality of spring-acting arms, two of which, as a a,serve as the actuating members and have diverging ends, as shown. Thesespring-acting arms are arranged side by side, and the two actuatingmembers a a are connected together at their lower ends, while the otherarms are arranged one between and one at and making provision forpivoting the hook box and a telephone-supporting hook adapt- 5 c at bothsides of the box said hook may be ed to be connectedwith either end ofsaid arranged at either end of said shaft, as shown switch-actuatingmechanism for operating it by dotted lines, Fig. 1, and hence may beloin the same direction, substantially as de- 5 cated at either side ofthe switch-box, and scribed.
